MDX - Simple Case Statement

For some reason I am getting an error on a Simple Case Statement
Error (1260052) – Syntax error in input MDX query on line 2 at token ‘)’
Case
When IS(Time.[JAN]) THEN Time.[Feb]
ELSE
Missing
End
Any suggestions.

Hi all,
I have a similar problem as i'm not too sure about the correct syntax I should use
CASE
WHEN IS(Time.CurrentMember, Descendants[2007]) THEN .......
ELSE
MISSING
END
How do I incorporate the check for Time.CurrentMember = Descendants of 2007???
Many thanks!

MDX simple case statement not working?

hi all - any idea what is wrong with this MDX statement? it is returning blank. I am trying to add a calculated measure using the below code but it is not working. thanks for the help.
CASE WHEN [Accounts].[Account Name].CURRENTMEMBER = "Cash" THEN
([Dates].[Hierarchy].currentMember.lastChild, [Measures].[Measures].[Amount]) END

If you are checking for the 'Cash' member of the Account Name hierarchy, do you need to do something like this?
CASE WHEN [Accounts].[Account Name].CURRENTMEMBER IS [Accounts].[Account Name].[Cash] THEN([Dates].[Hierarchy].currentMember.lastChild, [Measures].[Measures].[Amount]) END

CASE STATEMENTS AND CASE EXPRESSIONS IN ORACLE9I PL/SQL

CASE STATEMENTS AND CASE EXPRESSIONS IN ORACLE9I PL/SQL
=======================================================
PURPOSE
아래의 자료는 Case 문에서 oracle 8.1.7과 Oracle 9i의 New Feature로 8.1.7에서는
sqlplus 에서만 가능했고, 9i 부터는 pl/sql 까지 가능하다.
Explanation
1. Oracle 8.1.7 Feature
Oracle 8.1.7 에서 Case 문은 Decode 문과 유사하지만, 기존의 decode 문을 쓰는 것보다
더 많은 확장성과 Logical Power와 좋은 성능을 제공한다. 주로 나이와 같이 category 별로
나눌때 주로 사용하고 Syntex는 아래와 같다.
CASE WHEN <cond1> THEN <v1> WHEN <cond2> THEN <v2> ... [ELSE <vn+1> ] END
각각의 WHEN...THEN 절의 argument 는 255 까지 가능하고 이 Limit를 해결하려면
Oracle 8i Reference를 참조하면 된다.
The maximum number of arguments in a CASE expression is 255, and each
WHEN ... THEN pair counts as two arguments. To avoid exceeding the limit of 128 choices,
you can nest CASE expressions. That is expr1 can itself be a CASE expression.
Case Example : 한 회사의 모든 종업원의 평균 봉급을 계산하는데 봉급이 $2000보다 작은경우
2000으로 계산을 하는 방법이 pl/sql을 대신하여 case function을 사용할 수 있다.
SELECT AVG(CASE when e.sal > 2000 THEN e.sal ELSE 2000 end) FROM emp e;
Case Example : 나이를 column으로 가지고 있는 customer table을 예로 들어보자.
SQL> SELECT
2 SUM(CASE WHEN age BETWEEN 70 AND 79 THEN 1 ELSE 0 END) as "70-79",
3 SUM(CASE WHEN age BETWEEN 80 AND 89 THEN 1 ELSE 0 END) as "80-89",
4 SUM(CASE WHEN age BETWEEN 90 AND 99 THEN 1 ELSE 0 END) as "90-99",
5 SUM(CASE WHEN age > 99 THEN 1 ELSE 0 END) as "100+"
6 FROM customer;
70-79 80-89 90-99 100+
4 2 3 1
1 SELECT
2 (CASE WHEN age BETWEEN 70 AND 79 THEN '70-79'
3 WHEN age BETWEEN 80 and 89 THEN '80-89'
4 WHEN age BETWEEN 90 and 99 THEN '90-99'
5 WHEN age > 99 THEN '100+' END) as age_group,
6 COUNT(*) as age_count
7 FROM customer
8 GROUP BY
9 (CASE WHEN age BETWEEN 70 AND 79 THEN '70-79'
10 WHEN age BETWEEN 80 and 89 THEN '80-89'
11 WHEN age BETWEEN 90 and 99 THEN '90-99'
12* WHEN age > 99 THEN '100+' END)
SQL> /

70-79 4
80-89 2
90-99 3
Example
2. Oracle 9i Feature
Oracle 9i부터는 pl/sql에서도 case문을 사용할 수 있으면 이것은
복잡한 if-else 구문을 없애고, C언어의 switch문과 같은 기능을 한다.
아래의 9i pl/sql Sample 및 제약 사항을 보면 아래와 같다.
Sample 1:
A simple example demonstrating the proper syntax for a case
statement
using a character variable as the selector. See the section entitled
'Restrictions' at the end of this article for details on which PLSQL
datatypes may appear as a selector in a case statement or
expression.

when 'D' then dbms_output.put_line('The description was Fair');
when 'F' then dbms_output.put_line('The description was Poor');
else dbms_output.put_line('The description was No such Grade');
end case;
end;

Sample 2:
A simple example demonstrating the proper syntax for a case
expression
using a character variable as the selector. See the section entitled
'Restrictions' at the end of this article for details on which PLSQL
datatypes may appear as a selector in a case statement or
expression.

end;
dbms_output.put_line('The description was ' || description);
end;
- - - - - - - - - - - - - - - - Code ends here - - - - - - - - - - - -
NOTE: The above simple samples demonstrate two subtle differences in the
syntax
required for case statements and expressions.
1) A case STATEMENT is terminated using the 'end case' keywords; a
case
EXPRESSION is terminated using only the 'end' keyword.
2) Each item in a case STATEMENT consists of one or more
statements, each
terminated by a semicolon. Each item in a case expression
consists of
exactly one expression, not terminated by a semicolon.
Sample 3:
Sample 1 demonstrates a simple case statement in which the selector
is
compared for equality with each item in the case statement body.
PL/SQL
also provides a 'searched' case statement as an alternative; rather
than
providing a selector and a list of values, each item in the body of
the
case statement provides its own predicate. This predicate can be any
valid boolean expression, but only one case will be selected.

Fair');

Poor');

end case;
end;
- - - - - - - - - - - - - - - - Code ends here - - - - - - - - - - - -

the
type discussed in Sample 3 above.

end;

end;

Sample 5:
This sample demonstrates the use of nested case statements. It is
also
permissable to nest case expressions within a case statement (though
it
is not demonstrated here), but nesting of case statements within a
case
expression is not possible since statements do not return any value.

Sample 6:
This sample demonstrates nesting of case expressions within another
case
expression. Note again the absence of semicolons to terminate both
the
nested case expression and the individual cases of those
expressions.

Although PL/SQL anonymous blocks have been used in all of the examples
so far,
case statements and expressions can also be used in procedures,
functions, and
packages with no changes to the syntax.
The following samples are included for completeness and demonstrate the
use of
case statements and/or expressions in each of these scenarios.
Sample 7:
This sample demonstrates use of a case statement in a stored
procedure.
Note that this sample also demonstrates that it is possible for each
of
the items in the case body to consist of more than one statement.

제약 사항
다음의 databasetype은 case 문에서 지원되지 않는다.
BLOB

Nested Table
PL/SQL Record
PL/SQL Version 2 tables (index by tables)
Object type (user-defined type)
All of these types except for object types face a similar restriction
even for if statements (i.e. they cannot be compared for equality directly) so this is unlikely to change for these types. Lack of support for object types is simply an implementation restriction which may be relaxed in future releases.

NOTE:131557.1

I have done the following code but doesn't
like the statement of - "case(butNext)". What do you mean "doesn't like" -- did you get an error message?
I'm guessing it won't compile because you're trying to switch on a Button.
I tried something
like "g.fillOval(100,50,70,90, BorderLayout.NORTH)"...no that doesn't make sense. You only use BorderLayout.NORTH when you're adding components to a BorderLayout layout manager. An oval is not a component and fillOval isn't adding a component and Graphics is not a Panel or layout manager.
Would appreciate it if someone could tell me how to position
shapes using the graohic method. I think the problem is that you're confusing shapes with components.

Case Statement Issue

Hi All,
I need help figuring out a simple case statement. I need to add an OR condition to a couple of the statements and also have a condition that will return everyting. The first query works but lacks the OR condtion/statement. Any help is appreciated.
Select item_no
from item
where item_id =
case
when &p_item = '123' then '123'
when &p_item = '133' then '133'
when &p_item = '444' then '444'
end
How can i do the following?
Select item_no
from item
where item_id =
case
when &p_item = '123' then '123' or null
when &p_item = '133' then '133' or null
when &p_item = '444' then '444'
when &p_item = '999' then return all records
end

Hi,
Like Raghu, I wouldn't use a CASE espression. You can put conditions in a a WHERE clause jsut fione without CASE.
For example:
SELECT item_no
FROM     item
WHERE     (     '&p_item'     IN ('123', '133')
     AND     '&p_item'     = NVL ( item_id
                          , '&p_item'
OR     (     '&p_item'     IN ('444')
     AND     '&p_item'     = item_id
OR     '&p_item'     IN ('999')
OR     '&p_item'     IS NULL
;If you really, really want to use a CASE exprtession, then you can do something like this:
SELECT item_no
FROM     item
WHERE     CASE
         WHEN '&p_item'     IN ('123', '133')
         AND       '&p_item,'     = NVL ( item_id
                          , '&p_item'
             THEN '123, 133'
         WHEN '&p_item'     IN ('444')
         AND       '&p_item'     = item_id
             THEN '444'
         WHEN '&p_item'     IN ('999')
             THEN '999'
         WHEN '&p_item'     IS NULL
               THEN 'NO P_ITEM'
           ELSE NULL
        END     IS NOT NULL
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables, and also post the results you want from that data, for each of a few values of &p_item..
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using.

Case statement doubt

Hi,
I need some help with a simple case statement. lets say i have a table called name which has following 2 rows -
ID first_name last_name
1 JOHN SMITH
2 JOHN
i want to write a statement like :-
select id,case when first_name like '%JO%' then 'John in first_name'
when last_name like '%SM%' then 'Smith in last_name'
end result from sample_table;
The result displayed is -
1 John in first_name
2 John in first_name
how can i rewrite this query to also include a 3rd row which will display the result as -
1 John in first_name
2 John in first_name
1 Smith in last_name
I want to display this 3rd row which displays last name also.
Please help.

Please help.Hi,
welcome to the forum.
Please read SQL and PL/SQL FAQ
Additionally when you put some code please enclose it between two lines starting with {noformat}{noformat}
i.e.:
{noformat}{noformat}
SELECT ...
{noformat}{noformat}
What you want to achieve cannot be done with a single query without using some tricks.
Let's start from the point that your table has 2 rows. If you make a query without using a filter (A WHERE clause) and without using any CONNECT BY clause the number of rows returned by your query will be 2.
So a possible solution is to make a union of the same table applying the condition to select only records that you want to display.
i.e.:
First I select only records having first_name like '%JO%' then I make a union with all rows having last_name like '%SM%'WITH sample_table AS
SELECT 1 id, 'JOHN' first_name, 'SMITH' last_name FROM DUAL UNION ALL
SELECT 2 id, 'JOHN' first_name, NULL last_name FROM DUAL
SELECT id, 'John in first_name' txt
FROM sample_table
WHERE first_name like '%JO%'
UNION ALL
SELECT id, 'Smith in last_name' txt
FROM sample_table
WHERE last_name like '%SM%';
ID TXT
1 John in first_name
2 John in first_name
1 Smith in last_name

MDX -Children count function Not working in Case statement

Hi,
I am trying to create set when you slice with the Hierarchy member is leaf level , I want a output only that Leaf level .
and When I slice with the parent level , it has to give all the members below that parent level.
But the problem here is when I select child member or leaf member , The first condition in the Case is not working
WITH SET
TESTSET AS
CASE
WHEN
[Dimension].[Hierarchy].currentmember.children.count<0
THEN
[Dimension].[Hierarchy].currentmember
ELSE
DESCENDANTS([Dimension].[Hierarchy].Currentmember,,AFTER)
END
SELECT
WBSSET ON 1,
{} on 0
FROM
(SELECT {[Dimension].[Hierarchy].&[10]} ON COLUMNS FROM [CubeName])
Thanks,
Santosh

Hi Santosh,
I don't think Children count function not working in case statement, I have tested it on my local environment, here s the sample query for you reference.
with member
testset as
case
when
[Geography].[Geography].currentmember.children.count<10
then "X"
else "OK"
end
select testset on 0,
{[Geography].[Geography].[Country].members} on 1
from
[Adventure Works]
In your scenario, the issue might be caused by the query isself, you can try to use IsLeaf Funcion to achieve your requirement. Please refer to the links below.

Can't make simple 'IF' statement work in MS Query!?

I have read the existing threads on the subject but can't seem to make a simple 'IF' statement work in MS Query with a single table. I always get the following error:
Returns error message:
"Incorrect syntax near the keyword 'if'
Incorrect syntax near ','.
Statement(s) could not be prepared.
Here's my query (simplified, but not much):
select *
from table t
where t.modifieddate > if(t.active=0, date1, date2)
Just to see if I could get AN if statement to work, I've also tried:
SELECT t.active, if(t.active=0,2,3)
FROM CdmsTimeSheet.dbo.Registrations t
And
SELECT t.active, if(t.active='0','2','3')
FROM CdmsTimeSheet.dbo.Registrations t
And
SELECT t.active,
FROM CdmsTimeSheet.dbo.Registrations t
where datemodified>if(t.active='0',3/1/2014,1/1/2014)
and
SELECT t.active,
FROM CdmsTimeSheet.dbo.Registrations t
where datemodified>if(t.active='0',#3/1/2014#,#1/1/2014#)
I've been using excel/ms query for many years but not in the last year or two and am wondering if this was somehow removed? I tried using decode but then get a "not built-in function" error.
Please help! Thanks

Not sure what kind of database you are using. In SQL Server, you should use 'Case when' Statement Or 'IIF' function instead of if.
e.g.
select
top (10) BusinessEntityID,iif( BusinessEntityID=1 , 'true' , 'false') as test
from HumanResources.Employee
order by BusinessEntityID

Nope. This is two function calls. coalesce(a, b, c, ...) is just syntatic sugar for
   CASE WHEN a IS NOT NULL THEN a
WHEN b IS NOT NULL THEN b
WHEN c IS NOT NULL THEN c
   END
But if you use isnull it's a different matter. (But isnull() permits two arguments.)

Problem In Case Statement

HI ALL,
in the program,i need to display description based on condition type.
so we used CASE statement as below in LOOP. ITS not working .
could anyone please suggest if anything wrong in the following code.
LOOP AT gt_mat.
MOVE gt_mat-type TO gt_final-type.
Condition description
CASE gt_mat-type .
when 'N'.
move 'New' to gt_final-condes.
when 'B'.
move 'Block' to gt_final4-condes.
ENDCASE.
ENDLOOP.
please let me know whats the problem i above code and how to solve.
thanks in advance.

Hi,
The only solution for this could be to debug the program and check if the coresponding values are populated and available. You could also try to replace the CASE statement with a simple IF statement and check if its working.
LOOP AT gt_mat.
MOVE gt_mat-type TO gt_final-type.
* Condition description
IF gt_mat-type = 'N'.
gt_final-condes = 'New'.
elseif gt_mat-type = 'B'.
gt_final-condes ='Block'.
append gt_final.
clear gt_final.
ENDIF.
ENDLOOP.
Also make sure the case of the value in gt_mat-type matches with the condition

Need help in this query using Case Statement

I have the following query which is currently existing and I am adding few more conditions based on the new requirements which is based on a particular flag set as 1 or 0.
If it is set to 1 then I should use the old query as it is and if it is set to 0 then I should add the new conditions.
Basically when the flag is set to 0, I shouldnt be including some of the records that already exists and should include only new records. This is based on the plan_type_ids in (1,2,3,4).
Hence I am using the Case statement to check if the plan_type_id is in (1,2) then do a set of not exists and if the plan_type_id in (3,4) then do set of not exists.
But when I run this query it is giving me error. What am I doing wrong?
Is there any other simple way to combine all the not exists for all of those select statements as given after the line ------------------------- into a single one?
What am I doing wrong?
I tried putting the NOT EXists before the case too but that too didnt work.
Please help. Appreciate it.
Thank you in advance.

Case statement in where clause ??

Hello gurus,
Can we use case statements in where clause ?? Any example will be great!
And also i would like to know, besides CASE and DECODE statements, Is there any way we can use IF ELSE statements in SELECT clause or in WHERE clause ?
Thank you!!

Hi,

Hoek,
Thanks for the reply
Whatever you return from 'then' should match your criteria.I didnt get this part...can you elaborate this part ?? Thank you!!Remember what a CASE expression does: it returns a single value in one of the SQL data types (or NULL).
You're probably familiar with conditions such as
WHERE   col = 1Inthe example above, col could be replaced by any kind of expression: a function call, and operation (such as "d * 24") or a CASE expression, which is exactly what Hoek posted:
where case
         when col = 6 then 1
         when col = 9 then 1
       end = 1;I think what Hoek meant about mnatching was this: since the CASE expression is being compared to a NUMBER, then every THEN clause (as well as the ELSE, if there is one) should return the same data type. You can't have one THEN clause return a NUMBER, and another one in the same CASE expression return a DATE, like this:
where case
         when col = 6 then 1
         when col = 9 then SYSDATE     -- WRONG! Raises ORA-00932: inconsistent datatypes
       end = 1;
By the way, it's rare when a CASE expression really helps in a WHERE clause. CASE is great for doing conitional stuff in places where you otherwise can't (in the ORDER BY clause, for example), but the WHERE clause was designed for conditions.
Hoek was just trying to give a simple example. If you really wanted those results, it would be simpler to say:
where col = 6
or     col = 9and simpler still to say
where col IN (6, 9)

CASE Statement in IRR Compute(probable bug)

In IRR i am not able to create Compute with CASE statement. It is giving me error
"Invalid computation expression. THEN"
It is simple Compute
CASE WHEN A = 'SALES' THEN B + C ELSE B END
Also when i noticed the available functions(in Compute screen) THEN is missing.
Is it a bug? or I am missing something
Regards
Prabahar

I'm also running into this bug, though we're still back at Apex 3.1.1.
Has anyone figured out a workaround for it? I tried changing CASE to a DECODE, but I'm still getting an error. I'm having trouble understanding how any computation that used a function would pass this validation test.
Suggestions would be most welcome.
Thanks,
Stew

Use of decode/case statements

I am trying to use a decode or case statement to check for a particular field code of 'SIP' and if that is the value I only want half of the production figure used in the calculations for that field ('SIP').
The following code works well without the items commented out:
SELECT ALL
FINDER_WIS.PRODUCTION_HDR.END_TIME as prod_date,
'SCD' as district,

When I try to add the decode or case statement, I get ORA-00979; not a Group By expression as the error.
Can anyone assist me with this please?
Thanks in advance

Hi and welcome to the forum.
Simply put the field names you use in your DECODE also in your GROUP BY and it should work:
simple example:
MHO%xe> with t as (
2 select 1 col1, 1 col2 from dual union all
3 select 1 col1, 1 col2 from dual union all
4 select 2 col1, 2 col2 from dual union all
5 select 3 col1, 3 col2 from dual union all
6 select 4 col1, 4 col2 from dual
7 )
8 select col1
9 ,      decode(col1, 1, col2*100, col2)
10 ,      sum(col2)
11 from   t
12 group by col1 -->> NO col2 here...
13 order by col1;
,      decode(col1, 1, col2*100, col2)
FOUT in regel 9:
.ORA-00979: not a GROUP BY expression
Verstreken: 00:00:05.78
MHO%xe> with t as (
2 select 1 col1, 1 col2 from dual union all
3 select 1 col1, 1 col2 from dual union all
4 select 2 col1, 2 col2 from dual union all
5 select 3 col1, 3 col2 from dual union all
6 select 4 col1, 4 col2 from dual
7 )
8 select col1
9 ,      decode(col1, 1, col2*100, col2)
10 ,      sum(col2)
11 from   t
12 group by col1, col2
13 order by col1;
      COL1 DECODE(COL1,1,COL2*100,COL2) SUM(COL2)
         1                          100          2
         2                            2          2
         3                            3          3

Count Distinct Wtih CASE Statement - Does not follow aggregation path

All,
I have a fact table, a day aggregate and a month aggregate. I have a time hierarchy and the month aggregate is set to the month level, the day aggregate is set to the day level within the time hierarchy.
When using any measures and a field from my time dimension .. the appropriate aggregate is chosen, ie month & activity count .. month aggregate is used. Day & activity count .. day aggregate is used.
However - when I use the count distinct aggregate rule .. the request always uses the lowest common denominator. The way I have found to get this to work is to use a logical table source override in the aggregation tab. Once I do this .. it does use the aggregates correctly.
A few questions
1. Is this the correct way to use aggregate navigation for the count distinct aggregation rule (using the source override option)? If yes, why is this necessary for count distinct .. what is special about it?
2. The main problem I have now is that I need to create a simple count measure that has a CASE statement in it. The only way I see to do this is to select the Based on Dimensions checkbox which then allows me to add a CASE statement into my count distinct clause. But now the aggregation issue comes back into play and I can't do the logical table source override when the based on dimensions checkbox is checked .. so I am now stuck .. any help is appreciated.

Ok - I found a workaround (and maybe the preferred solution for my particular issue), which is - Using a CASE Statement with a COUNT DISTINCT aggregation and still havine AGGREGATE AWARENESS
To get all three of the requirements above to work I had to do the following:
- Create the COUNT DISTINCT as normal (counting on a USERID physically mapped column in my case)
- Now I need to map my fact and aggregates to this column. This is where I got the case statement to work. Instead of trying to put the case statement inside of the Aggregate definition by using the checkbox 'Base on Dimension' (which didnt allow for aggregate awareness for some reason) .. I instead specified the case statement in the Column Mapping section of the Fact and Aggregate tables.
- Once all the LTS's (facts and aggregates) are mapped .. you still have to define the Logical Table Source overrides in the aggregate tab of the count distinct definition. Add in all the fact and aggregates.
Now the measure will use my month aggregate when i specify month, the day aggregate when i specify day, etc..
If you are just trying to use a Count Distinct (no CASE satement needed) with Aggregate Awareness, you just need to use the Logical Table Source override on the aggregate tab.
There is still a funky issue when using the COUNT aggregate type. As long as you dont map multiple logical table sources to the COUNT column it works fine and as expected. But, if you try to add in multiple sources and aggregate awareness it randomly starts SUMMING everything .. very weird. The blog in this thread says to check the 'Based on Dimension' checkbox to fix the problem but that did not work for me. Still not sure what to do on this one .. but its not currently causing me a problem so I will ignore for now ;)
Thanks for all the help

Case statements to count Contact numbers

Hi,
I'm trying to use CASE IF or WHEN statements to count simple Contact numbers by owner or region. I need to count the following in separate fields of course:
Number of contact type = Customers
Number of Contact types = Propects
Number of Contacts at each seniority level (6 levels)
Number of contact validated (tick box)
I presume I need to write a CASE statement that I can then use to Sum for each column but I'm struggling with CASE statements to apply an CASE IF Column equals 'Customer' then count 1 for example. Never done these before so any help or advice greatly appreciated.
Contact type field is Contact."Contact Type"
Contact Seniority is Contact.PICK_3
Thanks,
Chris

here is an example:
sum (case when contact type = 'Customers' then 1 else 0 end)
Do the same for the second and forth in your list as above ;
include the Contact.PICK_3 and # of contact fields in step 1;
add region, owner, # of Customers, # of Prospects and # of validated in row section of your pivot view;
add Contact.PICK_3 to column section;
add # of contact to the measurement section.
